Bidding on lot of 2 VICTORIAN ADVERTISING TRADE CARDS for COHOCKSINK CARPET CLEANING WORKS in PHILADELPHIA.  Humorous/comic titled HARMONY & DISCORD.        My photos show the one on left as soiled or darker but in real view the 2 are both the same.   Measures 4  x 2 1/2 ".    Have very tiny marking at bottom right  "Copyrighted Rowley & Chew Print - Phila." 
                 Were evidently in an album at some point - have glue mark on backs.  Both have creases.     Fun images.
